Characteristics of Stainless Steel Heating Tubes

1. Small size, high power: This electric heater primarily utilizes clustered tubular heating elements, each with a maximum power of 5000kW.

2. Fast thermal response, high temperature control accuracy, and high overall thermal efficiency.

3. Wide range of applications and adaptability: This circulating heater is suitable for both explosion-proof and general applications, achieving explosion-proof ratings of Class B and Class C, and a pressure resistance of up to 20 MPa. The tube can be installed vertically or horizontally, depending on user needs.

4. High heating temperature: This heater is designed to operate at temperatures up to 850°C, a level unattainable by conventional heat exchangers.

5. Fully automated control: The heater's circuit design enables automatic control of parameters such as outlet temperature, pressure, and flow rate, and can be connected to a computer for human-machine interaction.

6. Long Life and High Reliability: This heater is manufactured using special electric heating materials, features a reasonable design power load, and incorporates multiple protection mechanisms, significantly enhancing its safety and lifespan.

7. The stainless steel heating tube features a metal tube as its outer shell. A spiral electric heating alloy wire (nickel-chromium or iron-chromium alloy) is evenly distributed along the tube's central axis. The interstices are filled with compacted magnesia sand, which offers excellent insulation and thermal conductivity. The tube ends are sealed with silicone or ceramic. This metal-clad heating element can heat air, metal molds, and various liquids. High-temperature heating wire is evenly distributed within the high-temperature stainless steel seamless tube, while the interstices are densely filled with crystalline magnesia powder, which has excellent thermal conductivity and insulation properties. This advanced structure not only provides high thermal efficiency but also uniform heat generation. When current flows through the high-temperature resistance wire, the heat generated diffuses through the crystalline magnesia powder to the metal tube surface, where it is then transferred to the heated component or the air, achieving the desired heating effect.
